    "abstract": "Recently, there have been several suggestions that weak Kerr nonlinearity can\nbe used for generation of macroscopic superpositions and entanglement and for\nlinear optics quantum computation. However, it is not immediately clear that\nthis approach can overcome decoherence effects. Our numerical study in this\npaper shows that nonlinearity of weak strength could be useful for macroscopic\nentanglement generation and quantum gate operations in the presence of\ndecoherence. We suggest specific values for real experiments based on our\nanalysis. Our discussion shows that the generation of macroscopic entanglement\nusing this approach is within reach of current technology.",
